Announcement. 


The demand for a light to take the place of oil and ordinary gas has 
been so great that we have given the subject very careful attention. 

Acetylene meets the requirements of this improved light. This gas is 
generated from Calcic Carbide by the use of water. 

After many experiments and a large expenditure of time and money, 
we have perfected an Automatic Generatoi for producing Acetylene from 
Calcic Carbide which is safe, economical, inexpensive, durable, reliable and 
in every way satisfactory. 

These generators in batteries are adapted to lighting cities, towns and 
villages through small and inexpensive mains. Small sizes are made for 
lighting churches, halls, theaters, houses and single rooms, and can also be 
used to take the place of the ordinary kerosene lamp for table use. 

We manufacture special generators for lighting ships, steam yachts, 
railway trains and street cars, and are prepared to furnish generators for 
light-houses and signal stations. 

We also make generators for special work, such as lighting elevators 
in buildings, etc. One form of these generators is particularly adapted to 
microscopic, stereopticon and photographic purposes. 

We solicit correspondence in regard to any special lighting required. 

Supplementary circulars will be issued from time to time giving infor¬ 
mation as to new applications of this light.

Acetylene Gas. 


THE LIGHT. 

PURITY. 

Acetylene Gas burns with a flame, the light of which resembles that of 
the sun more than any other known illuminant. Under its rays, which are 
the purest white, all colors and shades are accurately distinguished. 

POWER. 

A large incandescent lamp of ioo-candle power, when placed before 
the white glow of one small one-foot burner using Ac.etylene, will cast a 
shadow, showing that the latter is more powerful than the former. 

The filaments of incandescent lamps appear like “red-hot hair-pins,” 
as one observer graphically remarked. One one-foot burner using Acety¬ 
lene gives more light than six five-foot burners using ordinary gas. The 
small flame of Acetylene being equal to 125 standard candles, it follows 
that this is the ideal light for all purposes. Photometric tests show that a 
given area of Acetylene flame has 

Twelve and One=Half Times the Power of Ordinary Gas. 

Five Times the Power of an Incandescent Lamp. 


This alone makes the Acetylene light far superior to oil, gas or Edison 
lamp. Its color is also of the greatest advantage, but there are many other 

points of superiority.

Walmsley, Fuller & Co., Chicago. 


HYGIENIC ADVANTAGES. 

Lack of Heat. 

It is difficult to realize the small amount of Acetylene used in pro¬ 
ducing the wonderfully brilliant light, of which each one-foot flame is equal 
to six five-foot flames of ordinary gas. The six five-foot flames of ordinary 
gas use nominally thirty cubic feet of gas to give as much light as one flame 
burning one cubic foot of Acetylene; but really the six five-foot burners use 
over forty-five feet of gas as against one of Acetylene. Thus it is evident 
that the amount of heat delivered into a room from Acetylene is less than 
one-thirtieth that of ordinary gas, or about the same as the heat from the 
bulb of an incandescent lamp. Practically this amounts to nothing in the 
effect upon the temperature of a room. 

Complete Combustion. 

The combustion is complete and total, no portion of the gas escaping 
into the air of the apartment and vitiating it. The importance of this co? 7 i- 
plete combustion cannot be overestimated. It makes the difference between 
sickness and health. 

Incomplete combustion causes the formation of carbon monoxide , which 
is always produced when carbon is burned with an insufficient supply of 
air. Its escape into the room means not only a waste of fuel, but sickness 
and even death. “ Carbon monoxide when respired acts as a violent poison. 
Even when mixed with a very large quantity of air it produces giddiness 
and headache, and has in many instances proved fatal. Common coal gas 
contains from 4 to 7 per cent, of carbon monoxide, and the kind called 
1 water gas’ may contain over 30 per cent, of it.” (Youmans’ New Chem¬ 
istry, p. 188.) 

Complete combustion, on the other hand, forms carbon dioxide , which 
is always produced when carbon is burned in the presence of plenty of air, 
and which is the same gas as is exhaled from the lungs of animals in breath¬ 
ing. Every man exhales about 140 gallons of this gas per day. 

It is obvious that a flame using only one foot of Acetylene per hour 
will readily find plenty of air as the gas issues from the small holes of the 
burner; in proof of this it can be noticed that no blue zone is observable at 
the base of the flame which extends down fully to the orifice of the burner. 
Whereas it is equally obvious that five to eight feet rushing through a large 
burner, as common gas does, cannot possibly find enough air to burn 
completely. 

Fresh Air Retained. 

It is apparent from the above observations that in rooms where Acety¬ 
lene is used there will be not only no overheating , but also that the pro¬ 
ducts of combustion will not be noxious, as the quantity of carbon dioxide 
and water vapor produced is remarkably small, owing to the very small 
amount of gas used. 


Walmsley, Fuller & Co., Chicago. 


7 


One five-foot burner of ordinary gas produces an amount of carbon 
dioxide that equals the exhalations of about eighteen adults; while Acetylene 
products, with the same illuminating power, equal the exhalations of but 
three adults only. 

No Odor. 

There is positively no odor from the gas while burning, the flame 
being clear, white and steady, without smoke and with but little heat. 

Perfect Safety. 

Acetylene is safer to use than any other artificial light. This is abso¬ 
lutely true as regards the nature of the gas itself, the quantity used, and also 
the generator. 

Although Acetylene will asphyxiate the same as ordinary gas, it is less 
dangerous because its distinctive odor gives immediate notice of its pres¬ 
ence. Unlike coal gas which is somnific, or water gas which is without 
odor (hence difficult to detect and exceedingly dangerous), Acetylene has 
a pungent, penetrating smell, constituting a safeguard which is unique and 
very effective against leakage and ignition. When mixed with air there is 
the same danger as with ordinary gas, but the odor gives notice long before 

the dangerous proportions are reached. 

The largest Acetylene burner passes but one cubic foot per hour. The 
ordinary city gets jet passes not less than five feet in the same time. If 
therefore, a burner should be left open and unlighted, only one-fifth as much 
gas would escape, and the danger consequent fiom this cause alone is only 

one-fifth as great as that from using other gas. 

The “ Monitor ” Automatic Generator is almost as safe as a pail of 

water. An accident cannot happen except by sticking a light into it imme¬ 
diately upon opening, and even then would not be very serious, because of 
the small amount of gas in it. Less care is required in its use than with 
any oil light. Under no conditions would it be possible to exert a pressure 
sufficients cause an explosion. The only rule necessary to be observed 
for perfect safety is, not to bring fire near the generator when filling. 

Special Note. 

If five pounds of calcic carbide should be turned into Acetylene gas it 
would make about twenty-five cubic feet. If all of this were confined in a 
small room it would not make an explosive mixture with the air, but to do 
so would have to be confined with the air, in a closet nine or ten feet high 
and about five feet square, a condition of things which could not possibly 
happen unless purposely done. As the largest generators which can con¬ 
veniently be placed in a basement or ball do not hold at any one time more 
than ten cubic feet of gas, their safety is evident.

ECONOMIC ADVANTAGES. 

Cost. 

At the present writing,the cost of the Acetylene light is much less per 
candle power than ordinary gas light. At fifteen cents per pound for 
carbide, the gas costs three cents per cubic foot. But each cubic foot gives 
as much light per hour as thirty feet of the very best city gas, which at $2 
per thousand would cost six cents, and at $1.25 per thousand nearly four 
cents, for the same amount of light of poorer quality. 

The price of carbide in quantities will soon be not over ten cents per pound 
It is evident, therefore, that a more economical product is practically now 
offered, as well as one incomparably superior to common gas in every other 
respect. 

Cleanliness. 

The combustion being perfect, there is no smoke or smell whatever. 
But even if the smoke were the same as common gas, so little Acety¬ 
lene is used that there would be only one-thirtieth as much as with the 
latter. 

Fresco, wall paper, pictures, curtains and furniture retain their fresh¬ 
ness. 

Water is the only liquid used in the production of Acetylene, therefore 
no dirt attends the preparation of the gas. 

Manipulation. 

By reading the description of the “Monitor” Automatic Generators it 
will be seen how easy it is to generate the gas. No trouble is ever liable 
to be experienced. 

Color. 

The absolute whiteness of the light shows colors in their true nature 
and shades in their true relation. Consequently it can be used in painting 
or any work requiring colors and shades to be shown as in daylight. Work 
can be done at night which ordinarily must be put off until day. This fact 
alone makes it invaluable. 

For surgical and dental uses it shows the tissues as they really are, and 
prevents mistakes in night examinations. The same is true in regard to 
microscopic examinations. 

For showing paintings, flowers, dry goods, carpets, etc., and any ob¬ 
jects of delicate tints and shades, Acetylene may safely be said to be the 
only artificial light by which this truly can be done. 


Walmsley, Fuller & Co., Chicago.

Coolness. 

The small amount of gas used causes no more heat to be emitted than 
that given off by the bulb of an incandescent lamp. It is difficult to realize 
that seventy half-foot burners use only thirty-five feet of Acetylene per hour, 
yet give light equal to one thousand cubic feet of common gas, with a con¬ 
sequent lack of heat. In other words, this great light is produced with a 
consumption of no more gas than is used in four or five city gas jets. 

This lack of heat enables the light to be placed near the work, or by 
Surgeons and Dentists near the patient, without any inconvenience. For 
hospital or sick-room use this coolness is especially appreciated This 
more than doubly increases the value of the light, because, by bringing it 
close, the work has far greater illumination. 

Steadiness. 

The burners are so small that great variations in pressure, if they ever 
occur, are not noticed in the flame. The light burns, therefore, with more 
perfect steadiness than any other artificial light. 

Uniformity. 

Scientists the world over have approved Acetylene as a standard, be¬ 
cause its light is always the same, not only in intensity, but also in quality. 
The work done with this light as an illuminant at one time will be the same 
as at another; in other words, it can be depended upon at all times to be 
the same. This light will undoubtedly become the standard unit for photo¬ 
metric measurements, displacing the old uncertain candle power. 

Actinism. 

The chemical rays of this light are such as to adapt it readily to pho¬ 
tography, both as regards the exposure of the negatives and the printing 
from them. It is already in use in one large gallery in Chicago most suc¬ 
cessfully, and has completely displaced both the arc light and solar lantern 
for the making of enlargements.

ACETYLENE. 

What is it? 

Acetylene is a pure hydro-carbon gas chemically described as C2H2. 

Properties. 

It is clear, colorless and heavy, with a distinctive odor, burning with a 
flame of intense brilliancy. It is a vital principle of ordinary gas although 
present only to the extent of from ^ to P er cent. 

Distribution. , 

It may be handled and distributed in much the same manner as ordi¬ 
nary gas or by means much less complex. 

Elements. 

The elements employed are of the simplest character, being ground 
coke, lime, water and electricity. 

Calcic Carbide. 

Pure, unslacked lime and high-grade coke, both finely ground and inti¬ 
mately mixed, are submitted to the intense heat of the electric furnace un¬ 
der which they fuse down into a dark, crystalline, semi-metallic mass, known 
as Calcic Carbide or Carbide of Calcium. The most intense heat has no fur ¬ 
ther effect upon this material, but it has so great affinity for water or moisture 
in any form, that it cannot be exposed to the atmosphere for any length of 
time without loss from decomposition. It is therefore sold in air-tight 
cases only, in which it should be kept until needed for the actual manufac¬ 
ture of the gas. 


Generation of Acetylene. 

The actual generation is produced in an astonishingly simple manner. 
In a suitably arranged generator, the calcic carbide is brought into contact 
with water. A sort of double decomposition takes place. The oxygen of 
the water unites with the calcium of the calcic carbide, forming oxide of cal¬ 
cium which is precipitated to the bottom of the generator. The hydrogen 
of the water unites with the carbon of the calcic carbide forming Acetylene 
which rises and is used.

THE APPARATUS. 

THE FULLER “MONITOR” AUTOMATIC ACETYLENE GENERATOR. 

Patented. 

This Generator consists of two cylinders, one within the other, of pecu¬ 
liar shape. The Tank, or outer cylinder, has a recessed bottom (except in 
the smallest sizes), which saves weight of water and acts as a receptacle for 
the residue. In the larger sizes the residue can be drawn off from the bot¬ 
tom through a convenient opening. The Gasometer, or inner cylinder, is 
free to move within the Tank, and in the top carries the loading device for 
carbide, which is introduced in the smaller sizes through a clamp or screw- 
cap; in the middle sizes a water seal is preferably used, and in the largest 
sizes a special gas-tight trap. A suitable outlet is provided for the gas. 
The peculiar shape of the top of the Gasometer compensates, by less dis¬ 
placement of water, for the consumption of carbide and consequent loss of 
weight; thus helping to keep the pressure constant at the burners. 

The Purifier and Condenser. 

The Purifier consists of a double cylinder, one within the other; the 
inner one is provided with compartments which also act as condensers. 
The large Purifier is a coil of pipe in a water chamber with an enlargement 
for holding residue. 

The Burner. 

All fixtures may be the same for Acetylene as for ordinary gas, except 
the burner tips, which are very small; they fit regular fixtures. 

For special purposes special lamps have been devised. 

Special Advantages. 

First— The pressure does not at any time exceed the weight of the 
Gasometer and carbide, which per square inch is not over two ounces , and 
which is the same as city gas. 

Second— There are no valves of any kind to get out of order. 

T HI RD—The Apparatus is safer to manage than ordinary lamps. 

Full Directions Sent With Each Generator.

Walmsley, Fuller & Co., Chicago. 


ADVANTAGES. 

First, Generation—T he gas is not generated in our apparatus to a 
greater extent than used, thus preventing an accumulation and rendering 
a large gasometer unnecessary. 

Second, Steady Generation— The generation of gas is more steady 

than can be obtained in any other way. 

Third, Even Pressure— The pressure practically remains constant. 

Fourth, Adjustable Pressure— The pressure can be adjusted within 
certain limits to that best adapted to the purpose and number of burners. 

Fifth, Size and Weight— The apparatus is compact and equal to 
a gasometer twenty times the size. It is extremely light m weight. 

Sixth, Dry and Cool— The gas is dried first in the Generator and 
secondly in the Purifier so as to be delivered to the burners dry, clean, pure 
and cool. 

Seventh, Simplicity— The apparatus is extremely simple and requires 
no particular skill in manipulation. 

Eighth, Material— The apparatus is strongly made of those materials 
best suited to each part, and although light it is very strong. 

Ninth, Appearance— The appearance is handsome rather than other¬ 
wise. 

Tenth, Portability —The size and weight being so small, the appara¬ 
tus is easily carried about. 

Eleventh, Easy Manipulation— By reading the Directions it will be 
seen that the manipulation is simple, easy and not liable to cause any 
trouble. 

Twelfth, Durability— The simplicity and strength of the apparatus 
renders it very durable, it cannot get out of order. 


MODE OF OPERATION. 

Calcic Carbide is placed in the Generator and the stopcock opened 
as per Directions. As the air or gas escapes, the water rises until it comes 
in contact with the Calcic Carbide. Acetylene is at once generated and 
passing around the Calcic Carbide, is dried and the dampness absorbed 
produces more gas which rises into the upper part of the Generator. The 
Carbide in the annular space around the holder still further dries the gas. If 
more gas is generated than is used at once, the pressure of the gas forces 
the water away from the Calcic Carbide and generation almost ceases, 
continuing slightly owing to the water held by capillary attraction and as 
vapor. When the pressure reaches a certain limit the Generator rises so 
as to store under uniform pressure the gas produced. As the gas is used, 
the Generator descends and the operation is repeated.

PRACTICAL APPLICATIONS. 

GENERAL LIGHTING. 

Houses, Halls, Churches, Theaters, Hotels, Lawns, Gardens, Etc. 

The beautiful Acetylene light can now be used for domestic and public 
purposes. The apparatus should be selected to light the largest size and 
number of burners ever required at once for the longest continuous 
time. In other words it must supply the required number of cubic feet 
of Acetylene per hour, for a given number of hours continuously, before 
recharging. A larger apparatus should be selected if it is desired to re¬ 
charge at long intervals. It is better to consult us, however, giving the 
number and size of burners, the longest time they are to burn continuously 
and whether the Generator is to be charged daily or weekly; we should 
know also the height of the room in which the Generator is to be placed, 
and the width of entrance to the room. 

Generator. 

Like the boiler of a steam-engine, it is always better to select a Gen¬ 
erator of ample capacity. We can advise carefully whenever furnished with 
the information asked for above. 

Piping and Fixtures. 

The piping and fixtures may be the same as for ordinary gas; but if in¬ 
tended for Acetylene only, the main pipes may be much smaller, as only 
about one-thirtieth as much Acetylene need be used as ordinary gas. 

Burners. 

Ordinary gas tips cannot be used. We have devised burners especially 
adapted for Acetylene; these fit the regular pillars. 

Amount of Gas. 

Each pound of carbide will generate about five cubic feet of Acetylene, 
and each cubic foot of Acetylene is equal in lighting power to thirty cubic 

feet of common gas.

VILLAGES, TOWNS AND CITIES. 

At last all the advantages of general city lighting, together with the 
many special advantages of Acetylene, can be enjoyed by the smallest vil¬ 
lages and towns by the use of the “Monitor” Automatic Acetylene Gen¬ 
erators. Indeed not only is this possible, but it is done at a far less expense 
than city gas, both in regard to the first cost of plant and to the cost of the 
gas. 

Generator Plant. 

A village which would use 15,000 cubic feet of common gas per day 
would use only 500 cubic feet of Acetylene; this would be produced by a 
generator holding one hundred pounds of calcic carbide. An ordinary gas 
plant would require a fifty-foot lot for its furnaces, retorts and gasometer, 
with a number of attendants. Indeed its expense absolutely lorbids putting 
up a plant of this kind for so small a supply of gas, hence small towns have 
to do without gas. But two of our No. 7 “Monitor” Automatic Generators 
with condenser can be put in any room nine feet high by nine feet square, 
with one or two men as attendants. 

Two No. 10 “Monitor” Automatic Generators will furnish the equiva¬ 
lent of 150,000 cubic feet of common gas per day (enough for about 1,000 
to 2,000 inhabitants), and can be put complete in any room ten to fifteen 
feet high and fifteen feet square. One or two attendants are sufficient. 

For large towns several large generators may be used in batteries. 

Piping. 

As only one-thirtieth as much Acetylene is used as common gas, it fol¬ 
lows that the pipes may be much smaller. Practically a three-inch pipe with 
convenient tight screw connections will take the place of a heavy cast-iron 
eight or ten-inch main, with expensive, leaky, calked joints. When the expense 
of handling, laying and maintaining these large pipes is considered, it is evi¬ 
dent that these items of first cost and maintenance are so greatly reduced as 
to be practicable in small places as well as large. 

Indeed if the houses or other points of consumption are very much 
scattered, it is not necessary to carry the gas long distances in pipes, but 
only to distribute generators of desired size in rooms near the places of 
greatest consumption, using short pipes. In this case the number of at¬ 
tendants need not be increased, as one man can attend to several gener¬ 
ator stations.

SPECIAL LIGHTING. 

Single Rooms, Reading Lamps, Microscopes, Stereopticons, Photograph 

Galleries, Etc. 

The generator for these purposes is one of the smaller sizes, as men¬ 
tioned under the description of each generator, but the burners are 
different. 

The stand or bracket for single rooms or reading lamps may be at the 
taste and means of the purchaser, and the burner tip either *4-foot or i-foot 
or a cluster of these, with or without shades. For microscopic use a burner 
using less than l /%-foot of Acetylene per hour has been devised, which con¬ 
centrates the light to a brilliant point. The stereopticon burner is especially 
constructed so as to be readily adjustable. This produces an effect upon 
the screen which is equalled only by the electric arc or oxy-hydrogen light; 
but is, of course, much less expensive to maintain and less trouble to han¬ 
dle than either of these. 

For photographic use in making an exposure, one or more groups of 
burners on an adjustable stand are used, behind which suitable reflectors 
may be placed. A light equal to the electric arc in brightness can easily 
be obtained, while in actinic power it is much greater. The exposure varies 
from one to ten seconds. For printing from the negative a special lantern 
is used, on the smallest of which four printing frames may be placed at one 
time. With suitable paper a print may be made in a few seconds. For 
enlargements a burner similar to a stereopticon burner is used in a suitable 

camera. 

Boats, Railway and Street Cars, Elevators, Etc, 

Generators for these purposes are made to withstand the various 
motions and jars to which they are subjected, as described later. For small 
boats and carriages a modification of the smaller sizes enables them to be 
used as they are, but for larger boats a double swing frame to compensate 
for the roll and pitch is necessary. For still larger boats a swing for the 
roll is enough, and for very large ones both swings can be dispensed with. 

For cars and elevators the generator is either tall and narrow for placing 
in a corner, or broad and short for placing under the car or elevator. 

A burner which does not blow with the varying conditions is supplied 

for these purposes. 


i6 YValmsley, Fuller & Co., Chicago. 

Table and Ornamental Lamps. 

The “ Monitor” Generator, No. i, is made of various dimensions to 
take the place of the ordinary kerosene lamp in many cases, as a lamp for 
the table or to be placed with fancy shades in suitable vases for ornamental 
purposes, as hall or corner lights, piano lamps, etc. By sending us dimen¬ 
sions of founts and shades, we can in almost every case fit this generator to 
the ornamental parts. It can also be used as a hand lamp. 

Light Houses, Signal Stations and Buoys. 

The generators for this purpose are designed to furnish gas for a long 
time with perfect reliability and lack of watching. We solicit correspond¬ 
ence particularly in regard to these uses for which Acetylene' is especially 
adapted owing to its whiteness, great penetrating power and coolness, thus 
avoiding the danger of breaking lenses and shades. 


SPECIAL NOTICE. 

The “Monitor” Automatic Acetylene Generators have been designed 
for all purposes, using from one of the smallest tips, burning for a short 
time only, to any number of regular tips burning steadily or intermittently 
for a long time; and although better suited for the special purpose for which 
it is intended, each generator can be used for a great variety of work. 

For example, the Generator No. 3 can be used for the Stereopticon 
with the Quadruple Burner for several hours. The gas space is sufficient 
to allow the gas to be turned entirely off for a day or more. It is evident 
that the four burners can be used in as many rooms by proper connections, 
or that one burner only can be used for about four times as long. 

When great portability is desired, Generator No. 1 or 2 must be used, 
although No. 3 can be carried about without much inconvenience. The 
larger generators are not intended to be moved often. 

We recommend the Generator No. 3 as best adapted for a great variety 
of work with a small number of burners.

Generator No. i, Purifier and Reading Lamp. 

This Lamp is usually fitted with one half-foot burner which gives as 

much light as two ordinary gas jets. 

Half a pound of calcic carbide will last this lamp for five hours, of 
course longer if turned down slightly. Two such burners can be used with 
this Generator, if desired, on one or two standards. A one-foot burner may 

be used when more light is necessary. 

This Generator is usually 8 inches high and 6 inches in diameter, but 
is made in a great many shapes to suit various ornamental fittings. In 
several styles the generator forms the base of the lamp, and is one with it 
It can be used as a lamp for the table, piano, etc., for carrying as a hand 
lamp, for carriages, and wherever a small, portable or ornamental lamp is 

wanted. 

This Generator is usually filled from the under part of the inner shell. 
(See page 16.) Illustrated circular of the several forms is in preparation.

No. 3 should be used with it. 


Discount. 

The cost of running a pair of Optical Lanterns with dissolving key 
and quadruple burner at present prices of Calcic Carbide is about twelve 
cents per hour. A single lantern with double burner costs not over five 
cents per hour for the Acetylene consumed. It will thus be seen that not 
only is this the best light for the purpose, but the cheapest also.

TESTIMONIALS. 

As a rule we do not believe in publishing testimonials concerning the 
excellencies of any article, prefering that it should speak for itself. But 
in view of the fact that we are constantly receiving requests for them, 
we have concluded to give a few that have come to us unsolicited. 

Under date of May 5, 1896, Prof. Hamilton L. Smith, of Hobart Col¬ 
lege, Geneva, New York (who has been using our Generators since Febru¬ 
ary last), writes us as follows: 

“Today I put a charge of 2 ]/ z pounds Calcic Carbide in your No. 3 Generator, and must say 
here that Jor convenience and nice work , indeed for satisfaction generally , it could not be improved. 
The more I use it the better I like it, and I am very glad I did not return it, for I could not have 
made one on any different plan that would have been so satisfactory. I am more and more satis¬ 
fied with Acetylene as a substitute for Oxy Hydrogen.” 

Again under date of June 18th he writes: 

“I want to tell you what a beautiful exhibition I made last night with the Lantern, using 
your No. 3 Generator. The light burned perfectly , steadily , and with unchanging brightness to 
the end , and I had a picture 18 feet square with enough light to be perfectly satisfactory, the de¬ 
tails coming out very clearly. You can make what use you please of me to vouch for the per¬ 
formance, for I am quite sure the days of Oxy-Hydrogen are numbered .” 

Prof. Smith is an authority too well known in scientific circles through¬ 
out the country for us to say more as to his personality, or ability to judge 
the merits of Acetylene as an illuminant, and of our apparatus for gener¬ 
ating and burning it. 

“Chicago, June 15, 1896. 

“Messrs. Walmsley, Fuller & Co. 

« Gentlemen: —About three months ago I purchased of you an Acetylene Gas Apparatus, 
consisting of your ‘ Monitor’ Automatic Generator No. 3 and Quadruple Burner No. 6, for Optical 
Lantern projection, as a substitute for an oil lamp with four wicks, each two inches wide. 

' “I am delighted with it. My oil light is retired without regret. I find the Apparatus very 
simple and easy to manage. The light is intense but not harsh; the illumination is soft but sur¬ 
prisingly penetrating For use in the Stereopticon, Acetylene is the light for those who desire 
something far superioi to that of the best oil lamps. After being lighted and adjusted it needs 
practically no further attention, giving a steady white light, with no flickering, odor, noise or 
smoke. I use a size objective, giving a perfectly lighted 12-foot picture at a distance of 42 

feet from the screen. 

“In addition to my work with the lantern, I have used the Generatoi several times in light¬ 
ing my church, which is situated beyond the limits of the city’s gas supply. By actual compari. 
son it illuminated the large audience chamber of the church as well, if not better, than twelve 
bracket lamps with \'/ z -inch wicks and two ‘Mammoth Store Lamps,’ all with reflectors,—the 
Quadruple Lantern burner being placed in the gallery front, with two single burners about 25 feet 
apart on either side of it, connected by rubber tubing. The gas having been lighted, the appa¬ 
ratus was not touched until the light was extinguished after the service, neaily two hours later. 

“You are aware that this testimonial is positively unsolicited. 

“Rev. Ed. I. Goldschmidt, 

“Pastor St. Francis Xavier’s Church.”

“Gentlemen :— My ‘Monitor’ Automatic Generator No. 3 to hand O. K. Last night, using 
a 4.4 objective, I threw the light 40 feet on a dirty, chocolate-colored wall at end of a narrow 
hall. The work was O. lv. I do not propose to entirely give up Oxy Hydrogen, but in the ma¬ 
jority of places where I go, this Acetylene gas will serve me royally. It is a bother to be com¬ 
pelled to have compress gas shippeded a thousand miles. S. II. Kei.ton,
